Great mattress for the price. Firm but not too firm! Easy peasey to unpack!

Never had a bed in a box before and was skeptical. Bought for a cabin where it is used seasonally. It is very nice and better than a traditional mattress bought for the other bed there. Would buy again.

I got this to replace a very expensive spring mattress that got too soft too quickly (less than 2.5 years). That mattress was $700, while this one is just over $200. With the difference in price, you would think this one is not as good, but in actuality, it's better. I love spring mattresses for their firm support. I cannot sleep on just memory foam as they are too soft, and slumps where you need the most support, which is your buttocks and lower back. Memory foam sucks in where there is the most pressure, giving me extreme lower backaches. Memory foam works best when it's on top of a firm surface (but not too firm like the actual floor, although it could work on top of thick carpet). What I really appreciate about this mattress is it's hybrid, two-in-one form factor of having a memory foam on top of a spring mattress. To be honest, if the spring mattress was firm firm, that would have been ideal. Nonetheless, it's still pretty firm, and to further remedy the softness, I placed another thick mattress topper of top of that. So my set-up turned out to be three layers: 1) spring mattress 2) the built-in memory foam on top of that 3) topped off with a thick mattress topper. So in the end, this combination worked out almost perfectly, and for $220 for the mattress + built-in memory foam topper, this is an excellent deal. Even with my additional topper, it came out to under $300, much much less than the $700 of the previous mattress.

This was our second “bed-in-a-box” and we weren’t disappointed. PROS: • It arrived tightly rolled up, so the box can be maneuvered through small spaces (in our case, a narrow 1920’s staircase). • It did not have a strong smell upon opening, although we did air it out for several days before testing it. • It’s medium firm, making it good for a guest mattress. CONS: • It took roughly 1 day to “inflate” back to full-size. (This compares a bit less favorably to another other bed-in-a-box mattress from a different company, which sprung to full-size within moments. But, even so, I don’t think a day is very long to wait.) PS: This review is for UniPon’s “10 Inch Hybrid Mattress Full, Spring Mattress with Gel Memory Foam, Medium Firm.”

This is a great full size foam hybrid mattress. It arrives tightly rolled up and pops up over the day although it says to wait longer. It's a medium firmness like stated, and very comfortable. Granddaughter loves it on her new bed; and it's a fair price. It does need room to unfold; I used the floor, but you can put it on the bed and use it if that's the only place you have.

We are really impressed with this mattress. We gave it a full 72 hours before using it and trying it out and the mattress didn't disappoint. It gives great support and is very soft at the same time. We use it in our spare bedroom and everyone that has used it says that it's comfortable and that they sleep well. Definitely a high quality mattress that helps provide high quality sleep.

I thought the box of this would be huge but thankfully they were kind to roll it up into a tight box. Because of this I was able to retrieve and roll on my dolly easily. The bed itself is comfy with strong support!

This mattress exceeded all my expectations. Once I let it out fully expand got it set up it was extremely comfortable. Would recommend this mattress 10 out of 10.
